【问题描述】：

我想开发一个 vue3 应用程序并使用 rollup 作为捆绑器。我写了一个vue sfc

<template>
    <div>
        {{message}}
    </div>
</template>

<script>
    export default {
        name: 'TestComponent',
        setup(){
            const message = '123456';
            return {
                message
            }
        }
    }
</script>

<style lang="scss" scoped>
    .red{
        color: red;
    }
</style>

并在入口js文件中导入。

import Test from './Test.vue';

export default function (Vue) {
    Vue.component(Test.name, Test);
}

然后我安装了 rollup-plugin-vue 来编译 vue sfc、postcss 和 sass 来编译 sass。

const path = require('path');
const inputPath = path.resolve(__dirname, './src/index.js');
const outputUMDPath = path.resolve(__dirname, './dist/datav.umd.bundle.js');
const outputESPath = path.resolve(__dirname, './dist/datav.es.bundle.js');
const resolve = require('rollup-plugin-node-resolve');
const commonjs = require('rollup-plugin-commonjs');
const babel = require('rollup-plugin-babel');
const json = require('rollup-plugin-json');
const vue = require('rollup-plugin-vue');
const postcss = require('rollup-plugin-postcss');

export default {
    input: inputPath,
    output: [{
        file: outputUMDPath,
        format: 'umd', 
        name: 'datav-bundle', 
        globals: {
            vue: 'vue'
        }
    }, {
        file: outputESPath,
        format: 'es',
        globals: {
            vue: 'vue'
        }
    }],
    plugins: [
        resolve(),
        commonjs(),
        babel({
            exclude: 'node_modules/**', 
        }),
        json(),
        vue(),
        postcss({
            plugins: []
        })
    ],
    external: [
        'vue'
    ]
}

然后IDE报错： enter image description here

我也安装了@vue/compiler-sfc。

"@vue/compiler-sfc": "^3.0.6",

但模板仍未编译。

D:\LAB\DataVisualization\libs\src\index.js → dist\datav.umd.bundle.js, dist\datav.es.bundle.js...
[!] (plugin commonjs) SyntaxError: Unexpected token (2:4) in D:\LAB\DataVisualization\libs\src\Test.vue?vue&type=template&id=07bdddea&lang.js

我做错了什么吗？这是我的 package.json

  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",

}

标签： vuejs3 rollup

【解决方案1】：

哦，我想也许我知道原因了，我安装的是 rollup-plugin-vue@6.0.0-beta.6 而不是 *@6.0.0，编译成功！
